Shared by Miguel – this is Gomussa (or Gomuza), the son of Naomi and Kouch*, born in England in 1884. * Spencer Borden appears to have attributed Gomussa’s sire as the bay stallion Kars, which I find myself curious about, now – Naomi was red, and Kouch was grey, but Gomussa is bay. Kouch was probably heterozygous grey, but I have no idea what his base color was – black or bay**, if he is in truth the sire of Gomussa. I can’t find any discussion on this, though – anyone want to spitball? ** Interestingly enough, Kate and I were speculating a little bit ago that perhaps one of the reasons that black was seen so infrequently in the desert was not that it was necessarily ‘rare’, but because because black was generally not bred for, those born with black pigment were winners of the genetic lottery in that they had both a recessive ‘aa’ agouti expression AND at least one copy of grey. After all, all horses are born with either black or red as their base extension, with the agouti controlling whether a horse is black, or bay – with most non-grey horses presenting phenotypically as red…
